Summary: This study investigated the interaction of ZnO nanoparticles, Cr(VI), and Pannonibacter phragmitetus BB, and found that ZnO NPs inhibited Cr(VI) reduction but had no effect on bacterial viability. Cr(VI) induced BB to produce organic acids and release Zn2+ from ZnO NPs. The dissolved Zn2+ promoted Cr(VI) reduction, but hindered Cr(V)/Cr(IV) transformation.

Summary: By using mixed ligands to form a complex with Fe(III), the Fe-BDC/Fe-2MI composite was optimized at a specific molar ratio, leading to improved photoelectrochemical properties and enhanced photocatalytic activity for Cr(VI) reduction. The heterojunction structure resulted in a significantly higher pseudo-first-order rate constant for Fe-BDC/Fe-2MI compared to Fe-BDC and Fe-2MI, demonstrating superior performance with minimal loss in activity after multiple cycles.

Summary: In this study, unique layered Fe(III)-Cr(III) oxides were formed during the Cr(VI) removal by sulfate green rust (GRSO4). The layered structure of GRSO4 remained intact after fast reduction of Cr(VI). Further reduction of Fe(III) to Fe(II) using sodium dithionite resulted in stable Fe(II)/Fe(III) cycle in the hexagonal plates. The study observed better crystallinity at higher Fe(III) reduction rate and confirmed the layered metal oxide structure. Multiple treatment cycles showed increased Cr(III) loading on the layered Fe(III)-Cr(III) oxides. The study provides new evidence and insights for formulating strategies to eliminate Cr(VI) or related heavy metals.

Summary: Metal-organic frameworks (MOFs) have been widely studied for the removal of Cr(VI) from water. In this study, Fe-MOFs were successfully synthesized and immobilized in PAN nanofibers to create a composite electrospun nanofibrous membrane (PAN/MOFs ENFMs). The membrane showed rapid adsorption of Cr(VI) and maintained its adsorption capacity over a broad pH range. Immobilizing MOFs in ENFMs provides a new technological option for the removal of Cr(VI) from water.

Summary: Phytoremediation techniques, specifically involving the Streptomyces sp. Waksman & Henrici and Zea mays L. plant system, were found to be effective in removing lindane and Cr(VI) from contaminated soil. In co-contaminated systems, the presence of lindane was shown to enhance the removal of metal contaminants by interfering with their accumulation in plants. Additionally, the inoculation of Streptomyces sp. Z38 was found to activate defense mechanisms in plants, as indicated by a decrease in malondialdehyde concentration and an increase in superoxide dismutase activity.

Summary: This study found that Bacillus cereus SES, with the capability of reducing both Cr(VI) and Se(IV), demonstrated a faster reduction of Cr(VI) in the presence of Se(IV). Proteomics analysis revealed the mechanisms underlying the enhanced resistance and reduction of Cr(VI) by B. cereus SES in the presence of Se(IV). Moreover, the combination of Se and B. cereus SES showed potential for reducing the toxicity of Cr(VI) by affecting the bioavailability of both Cr and Se in soil.

Summary: The reduction of U(VI) to less soluble U(IV) species on mineral surfaces is a promising approach for remediating uranium contamination. Fe(II) is found to play a more reactive role than humic acid (HA) in this reduction process, and the extent of U(VI) reduction is determined by the Fe(II) content (n). When both HA and Fe(II) are present, two distinct mechanisms are observed: spectator mode, where only one acts as a reducing agent, and combined action mode, where both contribute to the reduction process.

Summary: Organophosphate esters (OPEs) are commonly used as additives in various industries, and they can have long-lasting adverse effects on the environment due to their inability to chemically bond with materials. A meta-analysis of 58 articles containing 2676 samples from 10 countries revealed that China had the highest concentration of OPEs in water resources, with over 715 μg/L for certain OPEs. Monte-Carlo simulations showed that despite concentrations being within acceptable limits, 95% of the population may still be at risk.

The results showed that the presence of Gd-doped ZnS QDs/g-C3N4 nanocomposite achieved the highest photocatalytic degradation efficiency and total organic carbon removal.

Summary: This paper extensively reviews the use of carbon-based materials, such as activated carbon, graphene oxide, and carbon nanotubes, for boron removal. It discusses the effects of operating conditions, kinetics, isotherm models, and removal methods. The study explores the impact of modifying the lifetime of carbon-based materials and concludes that modified materials have significantly higher boron adsorption capability. The addition of elements like tartaric acid improves the surface area, functional groups, and pore volume of carbon-based materials. Furthermore, the paper evaluates the health risks posed by boron in treated water and assesses the effectiveness of carbon-based materials for boron removal, along with future perspectives and research gaps.
